ATTACHMENT FOR HARVESTERS.

Application filed January 5, 1917.

To all whom it may concern: 7

Be it known that I, HENRY J. MENTINK, a citizen of the United States, residing at Gresham, in the county of York and State of Nebraska, have invented new and useful Improvements in Attachments for Harvesters, of which the following is a specification.

This invention relates to attachments for harvesters, and its principal object is to produce a simple and etlicient device to take the place of the ordinary reel for the purpose of bending or deflecting the incoming grain in the direction of the cutting apparatus.

A further object of the invention is to produce a device of the class described which will operate effectively on the grain without the beating actionof the reel. e

A further object of the invention is to eluding an endless conveyer adapted to engagethe grain, said conveyer being carried by a frame which is mounted for adjustment in various. directions to enable it. to operate successfully in connection with grain of various kinds and under varying conditions.

A further object of the invention is to produce a device of the class described which may be variously speedcd, and the speed of which may be changed by the operator while the device is in operation.

lVith these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In theaccompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications withinthe scope of the claims may be resorted to when desired.

In the drawings,

Figure 1 is a top plan view showing a portion of a harvester to which the invention has been applied.

Mounted on the platform, adjacent to the 2' inner and outer ends thereof, respectively,

,7 are supporting frames 20 and2l at the front corners of which shafts 22 are supported, each of said shafts carrying a pair of arms 23 between which a lever 24 is swingingly supported. The downwardly extending arms of the levers 24 support a shaft 25 which extends transversely through a frame B, said frame being pivotally supported on said shaft. The frame B is provided at the front and rear ends thereof with rollers 26 over which is guided an endless conveyer 27, said conveyer being equipped at suitable intervals with slats 28. A transmission chain 29 is suitably arranged to transmit motion between the shaft 25 and one of the rollers 26 for the purpose of driving the endless conveyer. v V

The shafts 22 are each provided with a radial armor crank 30, said cranks being connected by rods 3l'with similar cranks 32 that extend from a rock shaft 33 mounted on the frames 20, 21. One of the cranks 32 is extended upwardly to form a hand lever 34 having a stop member 35 engaging a rack segment 36 for the purpose of retainingthe hand lever and the parts controlled thereby at various adjustments. -The upwardly extending arms of the levers '24 are connected by rods 37 with arms or cranks of retaining ing the hand lever l0, the*levers 24 ma'y be rocked, thereby effecting adjustment of; the

frame B longitudinally with respect tothe harvest'er platform/and the machine of which'it forms a part. A V

The adjusting bar 43, aswell'as thel'eversBet and d0, are within convenient reach of the driver For the purpose of driving the conveyer 27- in any position "to which the conveyer' fframeB may be adjusted and for the pur- 35'; g "without "interrupting the motion of the con pose of varying the-speed, as may be desired,

The shaft 22 supported 'at'the; front cor- Tner ofgthe framev 20 adjacent'to the inner end of the, platform-supports a bell crank C having forwardly extending arm 65'and an upwardly "ex-tending armbG. The arm 65 has an arcuate slotted extension 67 whichis shdablyconnected with a sleeve 68; mounted on the headof thepinion 60. It will be seen that by rocking the bell crankon the shaft22; the pinion'may be'moved radially with respect to the disk 62', placingi'the pinion in engagement with any desired circumferential ser es'of'teethtl, Jthereby varylng the peed imparted to the disk 62andi the parts driven thereby- The arm fidof,

the bell crank G carries a dog 69'for locking engagement with a segment 7 Owhich is fiXed in-the shaft 22. The bell'cranl: C, when the dog 69is disengaged from the segment '70, may be rocked by means of 'a suitably guided operating rod 71 having a" handle 72, a flexible connection 73 being also provided so I r 2 whereby the dog" may be manipulated to release it from the segment, said dogbeing,
